Hi All, I'm having a horrific time getting exception handling to work in my C++ application which consists of an executable and three dynamic shared libraries. Library A defines the various exception classes. Library B throws one of these exception classes, and the executable attempts to catch them, however instead of catching the exception, the program exits by calling the terminate handler. I realize from the gcc manual that this has something to do with the exception type defined in my shared library not being recognized in the program that tries to catch it. I have not messed with any of the visibility attributes. I'm assuming that all symbols are exported by default. I have scoured the Internet looking for answers. As far as I know I am doing all the right stuff for this to be working. My application is running on Debian Linux (Lenny) 2.6.34. My gcc version is 4.4.3: Using built-in specs. Target: x86_64-linux-gnu Configured with: ../src/configure -v --with-pkgversion='Debian 4.4.2-9' --with-bugurl=file:///usr/share/doc/gcc-4.4/README.Bugs --enable-languages=c,c++,fortran,objc,obj-c++ --prefix=/usr --enable-shared --enable-multiarch --enable-linker-build-id --with-system-zlib --libexecdir=/usr/lib --without-included-gettext --enable-threads=posix --with-gxx-include-dir=/usr/include/c++/4.4 --program-suffix=-4.4 --enable-nls --enable-clocale=gnu --enable-libstdcxx-debug --enable-objc-gc --with-arch-32=i486 --with-tune=generic --enable-checking=release --build=x86_64-linux-gnu --host=x86_64-linux-gnu --target=x86_64-linux-gnu Thread model: posix gcc version 4.4.3 20100108 (prerelease) (Debian 4.4.2-9) I'm building each of my shared libraries with the following options: gcc -fPIC -shared -shared-libgcc -rdynamic -W1,--export-dynamic -Wl,-soname,libfoundation.so -o lib/libfoundation.so $(OBJECTS) -ldl My executable is built with these options: gcc -Wall -g -shared-libgcc When I try to run my application, it exits with the following error message: terminate called after throwing an instance of 'Execution::TEventHandle<Execution::EventBody>' I most definitely have a catch handler defined for this exception, which does work when exceptions of this type are thrown from within my executable program. When thrown from a shared library, the exception is not recognized and terminate() is called. Can anyone see what I might be doing wrong? Thanks in advance! Dallas
